No. llhll? 1Claims. (@Cl. 144 l} This invention relates to carpenter combinationpower tools.

An object of the invention is to combine several motordriven tools suchas a circular saw, a planer, and a belt sander, in a single handy unitwith a single motor arranged to drive any one of the several tools atthe option of the operator.

Another object is to provide a combination tool in which the operatormay change from one tool to another by opening the handle like the lidof a box, swinging it about the frame of the tool, and closing it again.

Another object is to provide a combination motordriven hand tool that issmall, light in weight, portable, attractive in appearance, simple tooperate, and of low manufacturing cost.

These and other objects will be readily understood from the followingspecification taken in connection with the drawings in which:

FIG. 1 is a perspective view of the invention;

FIG. 2 is a side view taken in the direction of arrow 2 of FIG. 1;

FIG. 3 is an end view with the belt sander in position for use;

FIG. 4 is a side view, taken in the direction of arrow 4 of FIG. 3,showing the hinged handle plate or cover closed in solid lines and openin dotted lines;

FIG. 5 is an end view partly in section taken on the line 5-5 of FIG. 4;

FiG. 6 is an end view similar to H6. 3 but with the handle plate orcover open and being swung into position for using the circular saw asindicated by arrow 3;

FIG. 7 is an end view of the other end of KG. 6 with end plate removed;

PK}. 8 is an end view similar to FIG. 3 but with the planer in positionfor use;

FIG. 9 is an end view partly in section taken on the line 5-5 of FIG. 4and showing the gearing arrangement for driving the planer;

FIG. 10 is a partial sectional view taken on the line iii-filo of FIG. 4showing the hinged plate cover in closed position;

FIG. 11 is an end view of the invention with the ci-rcular saw inposition for use;

FIG. 12 is an end view partly in section taken on the line 5-5 of FIG. 4and showing the gearing arrangement for driving the circular saw; and

FIG. 13 is a side view partly in section taken on the line 13-13 of FIG.12 showing how the motor assembly is rotatably mounted in the end plateof the triangular frame. 4

Referring to the drawings, triangular frame 14 has three peripheralfaces 21, 22, and 23. Circular saw 31, planer 32, and belt sander 33 areoperably mounted in frame 314 in positions corresponding to the threefaces 21, 22, and 23 respectively. Drive gears 41, 42, and 4-3 aremounted in frame 14 and are operably connected in any convenient mannerto circular saw 31, planer 32, and belt sander 33 respectively.

Motor 15 is axially and rotatably mounted in end plate 45 of triangularframe 14 and is provided with drive pinion lld. An assembly includinghandle 17, handle plate 18, and side plate 1.9 is pivotally mounted onmotor 15. Handle plate 18 is hinged to side plate 19 by hinge 2t and canswing between open and closed positions like the lid of a box. See FIG.4 and FLGS. 5, 6, 7, 8

Lock pin 28 may be turned by thumb nut 2% to lock the selector assemblyin any one of three positions corresponding to faces 21, 22, and 23respectively Handle 17 may include a switch (not shown) on extensioncord 25 which connects motor 15 with an outside source of power.

iidler gear 4i) is operably mounted on motor housing 15 and is always inmesh with and driven by drive pinion 16. As shown in FIGS. 1-5inclusive, the assembly is in position for using belt sander 33, idlergear 4-0 being in mesh with belt sander drive gear 43. Handle plate 18is locked in closed position corresponding thereto by lock pin 28.

To change from belt sander to planer, thumb nut 2-9 may be turned torelease lock pin 28; then handle plate 18 may be swung on hinge id tothe open position shown by dotted lines in H6. 4. FIGS. 6 and 7 showaxial views of the invention with handle plate 18 open and the assemblybeing swung from the belt sander position of FIGS. 1-5 to the planerposition whereupon handle plate 18 will be closed and locked as shown inFIGS. 8 and 9; then idler gear 40 will be in mesh with planer drive gear42.

in similar fashion handle plate 18 may be opened again and the selectorassembly swung another then closed and reloclccd in the circular sawposition shown in F163. 11 and 12 whereupon idler gear 40 will be inmesh with circular saw drive gear 41.

Operation of the several tools is well-known. It is clear that theoperator may readily select any one of the three tools and that only oneof them can be connected to motor 15 by idler gear 40 at any one time.

Having thus described the invention and its operation it is obvious thatthe objects as stated have been attained in a practical manner. While asingle embodiment of the invention has been shown and described, it isunderstood that changes may be made in the number and kind ofmotor-driven tools, and in the construction and arrangement of variousparts of the invention without departing from its spirit or scope as setforth in the following claims.

1 claim:

1. A carpenter combination power-driven hand tool comprising atriangular frame having three peripheral faces; a belt sander, a planer,and a circular saw operably mounted in said frame in positionscorresponding to said three faces respectively; a drive gear for each ofthe three tools; a motor coaxially and rotatably mounted in said frame;and means for selecting and operably connecting said motor with any oneof the three tools, said means including an assembly rotatable with, andabout the axis of, said motor, and an idler gear mounted onsaid assemblyand operably connecting said motor to any selected one of said threedrive gears.

2. A carpenter combination power-driven hand tool comprising atriangular frame having three peripheral faces; a belt sander, a planer,and a circular saw operably mounted in said frame in positionscorresponding to said three faces respectively; a drive gear for each ofthe three tools; a motor coaxially and rotatably mounted in said frame;and means for selecting and operably connecting said motor with any oneof the three tools, said means including an assembly rotatable with, andabout the axis of, said motor, an idler gear mounted on said assemblyand operably connecting said motor to any selected one of said threedrive gears, and a handle plate hinged to said assembly like the lid ofa box, said assembly being rotatable about the axis of said frame whensaid handle plate is open and being locked in position relative to theone of said three faces corresponding to the tool selected when thehandle plate is closed.
